Since cities have changed a lot, the size of the cities has grown
enormously. Discuss the causes and consequence of the enormous size of
cities.
Nowadays, the maps of cities are updated frequently. With the development
of city, more and more suburbs become parts of the city. When the cities in the
world are amplifying constantly, people discuss the topic hotly, the causes and
consequence of the enormous cities. Different people have different answers by
their respective views.
In my opinion, the evolution of society and the development of economy
result in the growth of the vast size of cities. Since the number of population
in every city is increasing continually, people need a large amount of space to
live in. With the progress of the technology, the output of crops rises sharply.
Fewer and fewer farmers are required, as a result, more and more villages
urbanize. The growth of the cities brings us many huge changes.
There are more job opportunities in the cities. For instance, China will
hold the Olympic Games in Beijing in 2008. The government is amplifying the size
of Beijing to build new gyms in order to hold it excellently. Obviously, people
in the cities could gain a lot of new jobs.
Of course, the enormous size of cities also has bad effects. Pollution is
becoming more and more serious all over the world with the amplification of the
cities. For example, the poisonous gas sent off by factories and automobiles has
made the air unhealthy for people to breathe. Water waste keeps pouring into
rivers and lakes; as a result, many water species are dying out. Furthermore,
more people the city have, more rubbish we can find.
In a word, since each coin has two sides, we should be acquainted clearly
with the reasons why the size of the cities has grown enormously and what it
will bring us. Thus, we could make full use of the positive effects and overcome
the negative effects. |
